4kg of second alloy could be mixed together.

Therefore, In 3kg of mixture,

Tin = 1kg

Iron = 2kg.

In 4kg of mixture,

Tin=(2/5)×4 = 8/5 kg=1.6kg

Iron=(3/5)×4=12/5=2.4kg

Therefore,Required ratio

=(1+1.6) : (2+2.4) =2.6 : 4.4

13 : 22

b) 58.23 L

c) 85.23 L

d) 58.32 L

b) 40

c) 42

d) 45

(x+5)/3x=1/2

=>2x+10=3x

=>x=10

Therefore, quantity of new mixture

=4x+5=45litres.

b) 60

c) 62.5

d) 64

water = 60 cc

Glycerine = 180 cc

Let x cc of water be mixed.

Therefore (60+x)/180 = 2/3.

==> 180+3x =360

⇒3x= 360 -180 = 180

Hence x=180/3 = 60 cc

b) 71 ml

c) 52 ml

d) 81 ml

Quantity of water =(2/9)*729 =162ml

Let `x` be the quantity that should be added to make the ratio 7:3.

According to the question, 567/(162+x) =7/3

=>1701 =1134+7x

=> 7x =1701 -1134

=>x=81ml

b) Rs. 525

c) Rs. 485

d) Rs. 450

b) 2 : 1

c) 2 : 3

d) 3 : 2

0.25x + 0.50y = 0.40(x+y)

25x + 50y = 40x + 40y

15x = 10y

x:y = 10:15 = 4:3

Amt of 25% is to Amt of 50% as 2 is to 3.

b) 182

c) 169

d) 130
